Well the storage that my boat is locked up in has a window that faces north. No big deal, except one side of my boat is getting sun almost all day from about 10am on as the sun goes from east to west and it's causing half of one side of the boat's white gelcoat to yellow, along w/ the rubrail. So I've fixed that problem, but now time to fix the boat.

It's just slightly yellow (enough for me to notice, not really enough for my friends to be able to catch it w/o me pointing it out). So should I just spend some time w/ the high speed polisher and some 3M rubbing compound or do you all think a regular boat (3M or meguiars) polish will work with some elbow grease?

If I go w/ the rubbing compound, do u think I need the micro-fine after or should I skip straight to the micro-fine for this job?

Nope. My first thought was that it had been stained by the "red" water at one particular lake here. But then I noticed it's only on the one side. It started off w/ just the rub rail starting to "yellow" all around. Now the one side is doing it faintly.
